40% of 210 is 525, and 1/4 of 210 is 52.5, so the answer is 40% of 210 > 1/4 of 210.

Step-by-step explanation:

Given: $f'(x) = x^2e^{2x^3}$ and $f(0) = 0$

We can solve for f(x) by writing

$\displaystyle f(x) = \int f'(x)dx=\int x^2e^{2x^3}dx$

Let $u = 2x^3$

$\:\:\:\:du=6x^2dx$

Then

$\displaystyle f(x) = \int x^2e^{2x^3}dx = \dfrac{1}{6}\int e^u du$

$\displaystyle \:\:\:\:\:\:\:=\frac{1}{6}e^{2x^3} + k$

We know that f(0) = 0 so we can find the value for k:

$f(0) = \frac{1}{6}(1) + k \Rightarrow k = -\frac{1}{6}$

Therefore,

$\displaystyle f(x) = \frac{1}{6} \left(e^{2x^3} - 1 \right)$

You have been saving $12 each week for many weeks. One day, you decide to count your savings and find that you have $384. Choose

Answer:

D or the last one.

Step-by-step explanation:

Honestly, you got me kinda confused. Is it saying that there is multiple equations to answer this? Well anyways, D would be the answer. When the variable (w) is beside the coefficient, it means you multiple them together. (W) standing for weeks multiplied by 12 which is how much you earn each week would get you the total amount. The rest just don't make sense.

new type of cell phone is being released to the public. The function below is used to predict f(t), the total sales in thousands

Answer:

40,000 units on the first day then 18% per week

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

$f(t) = f(0)(1+r)^{t}$

In which r is the rate of change, as a decimal.

In this question:

The number of phones sold in thousands of units per day, in t weeks since the date of release, is:

$f(t) = 40(1.18)^{t}$

Since $f(0) = 40$ , it solds 40,000 on the first week.

The rate of percentage increase is:

1 + r = 1.18

r = 0.18

So an increase of 0.18 = 18% a week.

So the correct option is:

40,000 units on the first day then 18% per week
